To all whom it may concern:

Be it known that I, PETRUs Hiinnnn, a subject of the King of Sweden, and resident of Centralpalatset, Stockholm, Sweden, have invented certain new and useful Improvements in Apparatus for Unwatering Concentrates, of which the following is a specification.

The present invention refers to certain ar-.

rangements for separating the water from concentrate of iron ore suspended in water such as comes from the magnetic separators and while still being in the conveyer truck. For this purpose the trucks are moved to a shaking apparatus arranged at a suitable place and it may be adapted for several trucks, the said shaking apparatus consisting of a rotating cam disk and an adjacent contrivance by means of which one end of the loaded truck can be lowered and elevated relatively to the cam disk and be brought into or out of its sphere of action.

In the accompanying drawings two forms of an arrangement according to the invention are represented.

Figures 1 and 2 show one arrangement in elevation seen from the side and from the end and Fig. 3 is a plan view with the truckbody removed. Figs. 4, 5 and 6 represent similar views of another form of the apparatus and Fig. 7 represents the same elevation as Fig. 4, the truck being elevated out of the way of the action of the cam disk.

Similar parts are indicated by the same letters of reference in the several figures.

In Figs. 1 to 3 A is a Decauville truck on the rails B. C are stationary stops against which the truck must be pushed for coming into the working position. 1) are pivoted props which, after the truck A has been pushed against the stops 0, are placed with their ends against the rear axle E as seen from the figures. F is an oaken plank (or the like) mounted on pivots G and provided with a handle H by means of which it can be turned. The plank F should occupy the position represented by dotted lines when the truck is moved forward. After the props D have been laid against the aXle the handle H is lowered into the position shown by full lines and is fastened by means of the chain I. The shaft K of the cam disk is then put into rotation in any suitable manner for instance by means of gearing and a belt connection from a motor, and every time the cam L strikes the cross bar M on the truck the end of the truck is elevated turning on the aXle E and after the cam has passed the end of the truck falls down on the plank F. After a number of such shocks the material in the truck has gathered at the bottom and the greatest part of the water flows above and may be poured off. The remaining concentratehas then the proper moisture for being directly formed into briquets and burned.

The form of apparatus shown in Figs. 4 to 7 differs from the one just described only therein that the part of the railway-track lying next to the stationary stops C, which should be fastened to the rails, is cut off and capable of turning on ournals N, mounted in end of said part of the track adjacent to the cam disk P which is elevated and moved into and out of engagement with the cam L. For this purpose there is a shaft R mounted in fixed bearings Q and provided with a handle S and two cam-shaped arms T, which are able to operate the ends of the rails. When a truck loaded with concentrated ore pulp is to be advanced to the shaking apparatus the sented in Fig. 7 the end of the railway track being then elevated andv the cross bar U brought out of the sphere of action of the cam L. After the truck has been pushed against the stops G and the props D have been turned against the aXle E the handle is moved upwards in the position shown in full lines in Fig. 4 coming then within the sphere of action of the cam L. In this form of apparatus both rails and truck are elevated and after each elevation the rails fall down against the stationary beam V which receives the shock. After the shaking has been finished the handle S is turned into the position shown in Fig. 7, the truck being carried away and the water removed. Several tracks may be arranged beside each other and the shaft K having a sufficient length may be provided with a cam disk P for each track in order to operate several trucks simultaneously.

I claim Apparatus for unwatering concentrates, comprising a wheeled truck carrying a tiltable receptacle for the concentrates and water, rails on which said truck is adapted to run, a stop or stops limiting travel of the handle S is moved into the position repre-v the stationary bearings O, and that it is the reciprocation to the receptacle/and means truck in one direction, means movable to S In testimony whereof I have signed my prevent motion in the other direction, va r0e name to this specification, in the presence of tating disk cam adapted to impart Vertical two subscribing Witnesses.
